摘要：

研究了由固体废物(炼铁废渣和炼钢废渣)制取的两种聚硅酸系混凝剂处理印染废水。结果表明,这两种聚硅酸系混凝剂不仅处理效果好,工艺简单,成本低廉,而且可以达到以废治废的目的,同时提高了废水的可生化性,为废水的后步处理打下了良好的基础。

Abstract:

Two kinds of polysilicate coagulant that are made from solid waste in iron-works to treat printing and dyeing wastewater.In accordance with the experiment, the result indicates that it is not only efficient, simple and convenient but also applicable for treating waste by using waste.So it is worthwhile to be spreaded widely .In addition, it improves the biodegradability of the wastewater, and ameliorates the post-treatment conditions.

Key words: printing and dyeing wastewater, coagulant, polysilicate, effluent treatment
